Notes

  • T5728 - Wetlands International 2012. Trend 1983-2007: + 2.6% p.a. ? Uncertain.
  • T2699 - 898. Trend 1983-2007: + 2.6% p.a. – Uncertain.
  • S8883 - This estimate tallies well with the estimates of 8,247 - 14,144 pairs (i.e. 25,000 - 42,000 individuals) for the breeding population in the Black Sea region without RU (BirdLife International 2015). The IWC count totals are always under 12,000 individuals in the last 10 years.
  • S9179 - BirdLife International (in prep.) estimated the breeding population size at 3,252 - 7,804 pairs in BG, GE, GR, MD, RO, TR, UA. However, the breeding population for European RU is estimated to be an additional 8,000-12,000 pair and the majority of these belong to this population, maybe 1,500 pairs belong to the Central European and the Caspian populations. This means that the size of the breeding population can be estimated at 9,752-18,304 pairs. Multiplying this by just 3, results in an estimate of 29,256-54,912 individuals. The highest annual IWC count total between 2014–2018 was 18,888 individuals (Nagy & Langendoen, 2020), but that is clearly based on incomplete counts. Rozenfeld & Mishenko (2018) suggested an estimate of 25,000-50,000 for this population and that is adopted here as the calculation based on breeding pairs relies on two assumptions: the number of pairs to be allocated to other populations and the conversion factor from pairs to individuals.
  • T7261 - RU reported a short-term population decrease of 30-49%. UA has also reported a population decrease, GR stable, MD increase, BG fluctuating without specifying its magnitude. GE, RO and TR reported unknown breeding population trend. In winter, MK reported a stable population, AL and UA decreasing, BG and MD fluctuating, GE, GR, TR and RO unknown and the long-term trend directions are similar (BirdLife International, in prep). The IWC trend analysis has also produced uncertain trends. During the 1998-2019 period the population had an overall declining tendency, but in the period of 2009-2018, partial recovery is suggested. Counts have clearly declined in RO and UA, but increased in RU (Nagy & Langendoen, 2020).
